DESCRIPTION

The massive flood in South Kalimantan motivated us to use our knowledge and ability to serve the country even though we are far away from it. It made us think, “what could we do with that amount of water?” Yet, at the same time, we are dealing with water scarcity, not also in Indonesia or Saudi Arabia, but all over the world. That was how an idea strut into our minds, “could we harvest rainwater for daily use?”. The answer is YES.

The first step would be harvesting the rainwater that has been filtered through several materials to eliminate dust and other dangerous materials. Then, the harvested water divided into two pipelined based on their purpose, saving and generating free electricity. For saving, it could be used for farming and even for drinking. To make sure that it is safe for drinking, the water is electrolyzed to separate ions to obtain clean water and safe for drinking.

For generating electricity, it used perpetual motion. This method has been going on for centuries. What makes our project special is that it uses rainwater. By that, we could use other sources of water for other purposes. We like to present this innovation as a sign of hope for everyone, especially Indonesians.
